Biogen (BIIB) Stock Forecast & Price Target
Biogen (BIIB) Analyst Ratings
Bulls say
Biogen's stock outlook is strengthened by a recent 35% increase in share price, reflecting a recovery not only from broader industry trends but also from the growth potential associated with its newer therapies, particularly Leqembi. The company's successful commercialization of key product launches, such as Leqembi, Skyclarys, and Zurzuvae, is expected to significantly contribute to revenue, with projections estimating $2.5-3.0 billion from these new products by 2030. Additionally, Biogen's strategic management initiatives to enhance operational efficiency and prepare for future growth create a favorable environment for the long-term financial performance of the company.
Bears say
Biogen's declining revenue from its multiple sclerosis (MS) franchise, which accounted for 45% of total revenue in 2024, poses a significant risk to the company's financial stability, especially with the anticipated launch of Sandoz’s biosimilar to Tysabri in November 2025, projected to pressure MS revenues down 6% in the second half of 2025 compared to the first half. Furthermore, the looming loss of exclusivity for Ocrevus in 2029 is expected to substantially decrease royalties, which could contribute to a negative EBITDA compound annual growth rate (CAGR) of -4% from 2026 to 2030, reflecting the impact of declining MS revenues. Additionally, uncertainties surrounding the commercial potential of newer franchises and the ongoing challenges with product launches, such as Skyclarys, further exacerbate the negative outlook on Biogen's future revenue growth.
